I had already logged in about 70 hours before the Steam release, so let me say that, for a price this small, this is definitely a game worth checking out.
The game's big gimmick is that the world's slowly getting gobbled up from the left side, which means you gotta keep on going to the right, which adds an element of urgency since you gotta plan your moves ahead of time or you're getting screwed over. And with eight different classes to choose from, each actually requiring you to play differently (like, you wouldn't head in solo with a bard or keep your backside exposed with a hero) and a whole bunch of perks to apply and combine in whoknowshowmany ways, in addition with too many possible worlds to traverse and daily campaigns AND a bit of writing here and there that, while often rather generic, still has a couple bits that might make you go "oh, I didn't expect that" the first time you encounter them, you'll more likely than not spend a lot of time on this, provided you're into games experimenting with the roguelike concept.
Presentation wise, it's a bit eh, though that's more of a personal issue. The music got annoying very quickly, so I turned it off. And the character portraits look rather amateurish and sketchy, but you don't see them too much, so they're easy to skim over.
Still, if you got the cash to spare, give it a shot.
